BMW 435 Common Problems & Reliability

Based on 961 MOT tests from 108 vehicles analysed by VehicleScore. The figures below describe that VehicleScore sample. Recurring issues seen in VehicleScore MOT data are not a claim that every BMW 435 has the same fault.

BMW 435's have a very good reliability rating of 749/999. The score was calculated from the average of every BMW 435 that has had a registered MOT.

We calculated all of the below figures by getting the score from each vehicle make/model/year/fuel, which are each calculated a score. We then generate the average score, taking into account factors such as mileage and emissions.

Common BMW 435 MOT problems

These groups combine equivalent MOT comments, such as the same tyre note on different corners. Counts are comment occurrences in the sample, not a percentage of cars.

Tyre wear

VehicleScore MOT data includes 146 advisory comments and 39 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record tyres that were worn, damaged, or close to the legal tread depth when the car was inspected.

What to inspect

Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.

Example MOT wording: OFFSIDE REAR TYRE WORN CLOSE TO LEGAL LIMIT/WORN ON EDGE (5.2.3 (E))

Brake disc wear

VehicleScore MOT data includes 73 advisory comments and 2 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record brake discs that were worn, scored, pitted, or corroded.

What to inspect

Look at the disc faces for deep scoring, a lip at the edge, and corrosion.

Example MOT wording: FRONT BRAKE DISC WORN, PITTED OR SCORED, BUT NOT SERIOUSLY WEAKENED (1.1.14 (A) (II))

Brake pad wear

VehicleScore MOT data includes 46 advisory comments and 2 failure comments in this group. Seen as both an advisory and a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record brake pads that were worn or below the inspection limit.

What to inspect

Ask for recent pad replacement and look at the remaining pad thickness.

Example MOT wording: REAR BRAKE PAD(S) WEARING THIN (1.1.13 (A) (II))

Steering rack issues

VehicleScore MOT data includes 10 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record play, a leak, or a damaged gaiter on the steering rack.

What to inspect

Check for play at the steering wheel and look for split rack gaiters.

Example MOT wording: OFFSIDE FRONT PLAY IN STEERING RACK INNER JOINT(S)

Oil leak

VehicleScore MOT data includes 9 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record an oil leak noted by the tester. Shock absorber misting is counted as a damper issue, not as an engine oil leak.

What to inspect

Look under the engine for fresh oil, and check the oil level.

Example MOT wording: OIL LEAK, BUT NOT EXCESSIVE (8.4.1 (A) (I))

Shock absorber issues

VehicleScore MOT data includes 8 advisory comments in this group. Seen mainly as an advisory. These are comment occurrences, not a share of all cars.

These MOT comments record shock absorbers or dampers that were leaking, misting, or insecure. A light misting of oil on a damper is not an engine oil leak.

What to inspect

Look for oil misting on the damper body and listen for knocks over bumps.

Example MOT wording: NEARSIDE FRONT SHOCK ABSORBERS HAS LIGHT MISTING OF OIL (5.3.2 (B))

Windscreen damage

VehicleScore MOT data includes 5 failure comments in this group. Seen mainly as a failure reason. These are comment occurrences, not a share of all cars.

These MOT comments record chips, cracks, or other windscreen damage in the driver’s view.

What to inspect

Look for chips and cracks, especially in the area swept by the wipers.

Example MOT wording: WINDSCREEN WASHER PROVIDES INSUFFICIENT WASHER LIQUID (3.5 (A))

BMW 435 MOT reliability by year

A model year is only commented on when VehicleScore has at least 5 vehicles from that year.

2018	6	35	97.1%	Tyre wear, Brake disc wear
2017	17	137	85.4%	Tyre wear, Brake pad wear
2016	28	236	88.6%	Tyre wear, Brake pad wear
2015	37	378	84.7%	Tyre wear, Brake disc wear
2014	15	144	90.3%	Tyre wear, Shock absorber issues

What to check when buying a used BMW 435

This is an inspection checklist based on MOT comments in the VehicleScore sample. It does not mean the car you are looking at has these defects.

Tyre wear. Check the tread depth and look for uneven wear, cracking, or damage on all four tyres.
Brake disc wear. Look at the disc faces for deep scoring, a lip at the edge, and corrosion.
Brake pad wear. Ask for recent pad replacement and look at the remaining pad thickness.
Steering rack issues. Check for play at the steering wheel and look for split rack gaiters.
Oil leak. Look under the engine for fresh oil, and check the oil level.
Shock absorber issues. Look for oil misting on the damper body and listen for knocks over bumps.
Windscreen damage. Look for chips and cracks, especially in the area swept by the wipers.

Buying a BMW 435?

Common problems tell you what can affect BMW 435s generally. VehicleScore can check the history of the actual car you're considering.

Where does this data come from?

VehicleScore analyses MOT histories from vehicles in its own dataset. Sample sizes vary by model, and a small sample is labelled as such. MOT data records roadworthiness and inspection defects. It does not capture every mechanical or electronic problem a car can have, and a comment on one test is not proof that the model has an inherent fault.
